a) Explain why antibiotics would kill a prokaryotic cell. (2 points)
Answer:
Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.
Explanation:
Sorry if this makes no sense. Basically, the antibiotics will harm/kill cells like the prokaryotic cell, but it won't harm or kill any human cells that are essential. They'll kill bacteria, though. The chemicals in the antibiotics aren't compatible with the ones in the prokaryotic cell, so it'll kill it.

Explain why two turns of the Krebs cycle are needed for each molecule of glucose ?
Two turns of the Krebs cycle are needed for each molecule of glucose
because glycolysis produces 2 molecules of pyruvate.
Glycolysis involves conversion of glucose to pyruvate after which it enters into the kreb's cycle to be converted into ATP which is the energy currency of cells.Pyruvate is the substrate-compound which enters into the kreb's cycle to form ATP. Since we are dealing with two pyruvates which are products of glycolysis then two turns are needed.Read more on https://brainly.com/question/25342836
In what stage of sleep do you experience a high level of motor cortex activity (the part of the brain involved in the planning, control, and execution of voluntary movements) that is blocked by the brainstem, leaving you more-or-less temporarily paralyzed?
Answer: REM
Explanation:
There are four stages, 3 of them are non-REM stages, (or NREM) and obviously, the other is the REM stage.
We are looking for a stage where your body becomes "paralyzed".
This would be the REM sleep stage.
This is the stage where most of your dreams happen, and that is why your body is more-or-less paralyzed, so you do not move while dreaming.
There are other characteristics, like irregular (and faster) breathing and an increase in blood pressure and heart rate.

Which title best reflects the main idea of the passage?
The Sun transfers energy in the form of heat to Earth through radiation. The ground gets warmer as heat flows from one ground particle (such as soil particles or rocks) to another. The ground heats up the air above it through conduction when the particles of air absorb heat from the particles of the ground. Heat also flows from the ground to the air through radiation. The warmed mass of air becomes less dense and rises. As it rises, it loses heat to the environment, so it cools and becomes more dense. The cool, dense air sinks and takes the place of the warm, less dense air. This convection process transfers heat from Earth’s surface to the atmosphere and moves heat around Earth.

Answer:
DNA is copied and transcribed into another form. This smaller segment is made of genes.
Explanation:
Cell growth, replication, and cell repair are controlled by genetic material found within DNA molecules. These deoxyribonucleic acids' long-chain helical macromolecules are assembled from complex sequences called nucleotides; strong covalent bonds attach these four monomers (adenine, cytosine, guanine, thymine).
Coding regions of DNA are called genes- they contain specific instructions for the cell. Genes can include multiple nucleotides and even several chromosomes. Gene expression typically includes transcription into RNA, and translation into amino acids/ proteins.

what are NADH and FADH ? why are they important
Answer:
NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.
Explanation:
Answer: Here you go!
NADH: NADH is the abbreviation for the naturally occurring biological substance, nicotinamide adenine dinucleotide hydride. ... Often referred to as coenzyme 1, NADH is the body's top-ranked coenzyme, a facilitator of numerous biological reactions.
FADH: Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain. Nicotinamide adenine dinucleotide, or NADH, is a similar compound used more actively in the electron transport chain as well.
WHY ARE THEY IMPORTANT??
ATP production is an important part of cellular respiration (the process of generating energy from food) and both NADH and FADH2 that are involved in this process help in making more ATP. ... NADH and FADH2 that act as electron carriers give away their electrons to the electron transport chain.

Answer: B
Explanation:
The pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents. So, the correct option is (B).
What are Genes?
A gene is the basic physical and functional unit of heredity which are made up of DNA. Every person receives two copies of each gene which is inherited from each parent.
Most genes are the same in all people but there are small number of genes which are slightly different between people. Genes are made of DNA, so each chromosome contains many genes. Genes carry the information that determines traits and characteristics or features that are passed on to other organisms or inherited from parents.
Each cell in the human body contains about 25,000 to 35,000 genes.
Thus, the pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents. So, the correct option is (B).

Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondrion with the energy needed to join small molecules together. (6 points)
pls help asap :)
Answer:
you combine all the molicules
Explanation:
A concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondria with the energy needed to join small molecules together through ATP. The H+ ions are pumped across by membrane “pump proteins” into a space bounded by memb ranes that contain numerous amounts of hydrogen ions. Then, electrons are passed from o ne membrane-bound enzyme to another, which causes some energy to get lost during eac h transfer. This “lost energy” allows the pumping of hydrogen ions against the concentratio n gradient. After all the steps are taken, the mitochondrion will be provided with the energy needed to join small molecules together.

Suppose the DNA sequence GCT ATA TCG was changed to GCTАТТ TCG. How would the products of translation, the amino acids, be affected ?
Answer:
The outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of codons, or groups of three nucleotides. ... Each word itself has a separate meaning, as each codons represents one amino acid.
Explanation:
hope it helps.
have a wonderful day!
In the given DNA sequence GCT ATA TCG, the second codon is changed from ATA to АТТ.
This change would affect the products of translation, which are the amino acids. To determine the amino acids, we need to refer to the genetic code, which translates each codon into a specific amino acid. The codon ATA corresponds to the amino acid isoleucine (I), while the codon АТТ also corresponds to isoleucine (I).
Since both codons, ATA and АТТ, code for the same amino acid (isoleucine), the change in the second codon would not affect the amino acids produced during translation. Therefore, the products of translation, the amino acids, would remain unaffected by this change.
